Abstract
New grade of sodium perborate anhydrous obtained from dehydration of sodium perborate monohydrate, wherein the ratio by weight of sodium perborate monohydrate to sodium oxoborate is at least 1.5:1, method of manufacturing and use thereof in detergent compositions are disclosed. The new grade of sodium perborate anhydrous is particularly suitable for use in non-aqueous liquid detergent compositions to improve dispensing behavior without impairing the chemical stability of formulations comprising a peroxy acid bleach precursor, especially N,N,N',N'-tetraacetyl ethylene diamine.
